Marble, a type of metamorphic rock formed under high temperature and pressure inside the earth's crust that change any original rock formation. All kinds of internal force in the earth's crust makes original rock qualitative changed. Marble is mainly composed of calcite, limestone, serpentine and dolomite, whose main ingredient is calcium carbonate, accounting for about 50%. Other include magnesium carbonate, calcium oxide, manganese oxide and silicon dioxide. Marble is a crystalline substance which consists of limestone or dolomite by regional metamorphism. Mineral ingredient is calcite, bubbling in hydrochloric acid, regular or irregular blastic texture, particle thickness is different.

Technological Process

Marble processing mainly include feeding, crushing, screening, grading. So the main use of equipment are vibrating feeder, jaw crusher, cone crusher, and circular vibrating screen. We produce a series of crusher, milling machine, sand making machine and other marble crushing&grinding equipment. But according to different purposes and different material of marble, we need to choose the different vibrating feeder, jaw crusher, cone crusher, circular vibrating screen and other matching accessories, to be able to meet the requirements of the customers.Depending on the type of crushing, marble crusher is divided into jaw crusher, impact crusher, hammer crusher and cone crusher. How to choose the suitable type of crusher? When the input partical size between 125 mm to 1020 mm, marble can be rough crushed through the jaw crusher; use impact crusher when the material particle size is 100-500 - mm. The greatest advantage of impact crusher is discharging opening can be adjusted automatically according to the needs of users. Hammer crusher commonly used in crushing coal, limestone, and marble occasionally. Cone crusher has large crushing rate, low energy consumption, good uniform shape of final products, suitable for middle and fine crushing. Marble crushing production line mainly used for fine process of marble particles. Different industries is corresponding with different requirements of final size, therefore, reasonable design of marble crushing production line is necessary.Productive process of marble production line: Hopper - > Vibrating Feeder - > Jaw Crusher (primary crushing equipment) - > Cone Crusher (secondary crushing equipment) - > Vibrating Screen - >Conveyor - > Final Product.

Application Fields

With the development of modern architecture, the key factor of choice of decoration material is becoming lightweight, high strength, beautiful, and multispecies, so the application of the marble is becoming more and more popular. Marble is mainly used for processing into various shaped materials, plank, building metope, ground, table, column, tablet, tower, statues and so on. It can also be carved in marble arts and crafts, stationery, lamps and lanterns, utensils, and other practical works of art.
